Modern surgical care must meet high standards of quality but must also be cost-effective. Critical care uses huge amounts of resources, and strategies for effective use of scarce, expensive intensive care unit beds must be implemented. Previously, we demonstrated that ancillary expenditures can be decreased without compromising care. The present study was performed to determine whether our cost-containment strategies were durable and could be extended to areas, such as chest roentgenography, where savings previously proved elusive. ⋯ Durable reductions in physician-ordered ancillary expenditures are possible without compromising the standard of care of critically ill patients, but active management and daily reinforcement are necessary to the process. Shorter length of stay and lower costs benefit the patient, the surgeon, the intensivist, and the institution.

The purpose of the present study was to test the association between on-site intravenous fluid replacement and mortality in patients with severe trauma. The effect of prehospital time on this association was also evaluated. The design was that of an observational quasi-experimental study comparing 217 patients who had on-site intravenous fluid replacement (IV group) with an equal number of matched patients for whom this intervention was not performed (no-IV group). ⋯ The results of this observational study have shown that the use of on-site intravenous fluid replacement is associated with an increase in mortality risk and that this association is exacerbated by, but is not solely the result of, increased prehospital times. Our findings are consistent with the hypothesis that early intravenous fluid replacement is harmful because it disrupts the normal physiologic response to severe bleeding. Although this evidence is against the implementation of on-site intravenous fluid replacement for severely injured patients, further studies including randomized controlled trials are required to provide a definitive answer to this question.

Multicenter Study
Probability model of hospital death for severe trauma patients based on the Simplified Acute Physiology Score I: development and validation. Archivio Diagnostico.
We evaluated whether or not the Simplified Acute Physiology Score (SAPS) I is a suitable audit system for trauma patients admitted to general intensive care units (ICUs). A probability model for SAPS I was retrospectively assessed on trauma patients admitted to general ICUs from 1990 to 1992. Because it was determined that SAPS did not fit the data well, we developed a customized probability model of SAPS I for trauma patients and validated it prospectively on an independent data set (patients admitted to general ICU in 1993-1994). Measures of calibration (goodness of fit) and discrimination (receiver operating characteristic curve) were adopted to assess the performance of the model. ⋯ Customization of SAPS I for trauma patients has shown good calibration and high discriminatory power in Italian ICUs and when applied to an independent data base. The advantage of customization would be the collection of the same set of variables for all patients admitted to ICUs against the use of specific scoring systems.
